Abstract
Preparation of novel hybrid catalysts with highly stable properties was conducted for wastewater remediation. A facile method was employed to prepare a Fe, Cu bimetallic/Fe3O4/metal-organic framework with coordination sites (Fe3O4@MOF/Fe-Cu/CUM) as a catalyst. The structure and composition of the prepared catalysts were studied using various methods (X-ray diffraction spectroscopy, scanning electron microscopy). A Fenton-based method was applied upon cephalexin to study the catalytic progress of the synthesized Fe3O4@MOF/Fe-Cu/CUMcatalysts. Fe3O4@MOF/Fe-Cu/CUMhad the best catalytic performance compared with that of the other catalysts. Fe3O4@MOF/Fe-Cu/CUMcould accelerate the decomposition of H(2)O(2)into OH and O(2)(-)as important scavenger species in the removal of cephalexin. Fe3O4@MOF/Fe-Cu/CUMhad neutral pH, and their acutely stable performance could be preserved in five cycles with a low rate of ion leaching.
